Jeroen Mengerink presented on test process improvement in Agile environments. He discussed how current TPI models focus on testing and structure but may not apply well to Agile. He proposed maturity levels for Agile testing - forming, norming, and performing. The presentation provided an assessment model to evaluate key areas like teamwork, test management, and regression testing. It offered examples and recommendations for improving processes in an Agile way, focusing on people, the development process, and testing flexibly.
